Circumstances and Investigation Findings
How and Why the Fire Occurred
Police investigations determined that Jonghyun died from smoke inhalation and burn injuries in a residential fire. The apartment door was locked from the inside, and there were no signs of forced entry. Officials found no evidence of foul play or accelerants, leading to the conclusion that the fire started inside the unit. A forensic autopsy highlighted severe smoke inhalation as the primary cause. The locked door and rapid fire progression contributed to the fatal outcome.

Depression and Its Role
Posthumous reports and investigations indicated Jonghyun had been managing depression. While depression is a complex health condition, in his case it influenced circumstances around his final days. Authorities noted that his mental health struggles were a factor in the environment leading up to the fire, though the immediate cause of death remained physical injuries from the fire.
